Hi Mirek,

Well, that was interesting. I did some benchmarking and the looper is indeed a clear winner when there are a lot of small jobs to handle.

I further simplified the syntax for a "i = 0 .. n-1" -type of loop with a simple macro:

#define PARALLEL_LOOP(_ICOUNT_,_OPERATION_) { CoWork _co_; _co_ * [&] { for(int i = _co_.Next(); i < _ICOUNT_ ; i = _co_.Next()) { _OPERATION_; } };}

So, I can run the loop with:

PARALLEL_LOOP(n, operation(ib[i]));

Thanks and best regards,

Tom
